    <p> Calls a NAnt target in the current project. </p>
    <p> When the <a href="../tasks/call.html">&lt;call&gt;</a> task is used to execute a target, both that target and all its dependent targets will be re-executed. </p>
    <p> To avoid dependent targets from being executed more than once, two options are available: </p>
    <ul style="list-style-type: disc;">
      <li> Add an "unless" attribute with value "${<a href="../functions/target.has-executed.html">target::has-executed</a>('<code>&lt;target name&gt;</code>')}" to the dependent targets. </li>
      <li> Set the <code>cascade</code> attribute on the <a href="../tasks/call.html">&lt;call&gt;</a> task to <b>false</b> (<code>recommended</code>). </li>

    <h3>Examples</h3>
    <ul class="examples">
      <li>
        <p> Call the target "build". </p>
        <pre class="code">
&lt;call target="build" /&gt;
    </pre>
      </li>
      <li>
        <p> This shows how a project could 'compile' a debug and release build using a common compile target. </p>
        <pre class="code">
&lt;project default="build"&gt;
    &lt;property name="debug" value="false" /&gt;
    &lt;target name="init"&gt;
        &lt;echo message="initializing" /&gt;
    &lt;/target&gt;
    &lt;target name="compile" depends="init"&gt;
        &lt;echo message="compiling with debug = ${debug}" /&gt;
    &lt;/target&gt;
    &lt;target name="build"&gt;
        &lt;property name="debug" value="false" /&gt;
        &lt;call target="compile" /&gt;
        &lt;property name="debug" value="true" /&gt;
        &lt;call target="compile" /&gt;
    &lt;/target&gt;
&lt;/project&gt;
    </pre>
        <p> The <code>cascade</code> parameter of the <a href="../tasks/call.html">&lt;call&gt;</a> task defaults to <b>true</b>, causing the "init" target to be executed for both the "debug" and "release" build. </p>
        <p> This results in the following build log: </p>
        <pre class="code">build:
  
init:

    [echo] initializing
    
compile:

    [echo] compiling with debug = false
    
init:

    [echo] initializing
    
compile:

    [echo] compiling with debug = true
    
BUILD SUCCEEDED
  </pre>
        <p> If the "init" should only be executed once, set the <code>cascade</code> attribute of the <a href="../tasks/call.html">&lt;call&gt;</a> task to <b>false</b>. </p>
        <p> The build log would then look like this: </p>
        <pre class="code">build:
  
init:

    [echo] initializing
    
compile:

    [echo] compiling with debug = false
    
compile:

    [echo] compiling with debug = true
    
BUILD SUCCEEDED
  </pre>
      </li>
    </ul>
